“…Downstream the SMX (Z2, P1) I max linearly increases from 60% to 80%, these values are of the same order of amplitude than the ones giving by Ref. [33]. These authors studied and compared the circumferential turbulence intensity evolution of flow through SMI, KMA and Oxynator ® static mixers with a gas injection.…”

“…The compared evolution of the turbulence intensity downstream, upstream and within the static mixer is examined. This information will allow estimating the index of mixing which is proportional of the turbulence intensity (Ting et al [32] and Barrué et al [33]). …”

“…The review paper of Thakur et al [8] provides a nice summary that discusses in what applications static mixers are beneficial and to be preferred above stirred vessels and other conventionally agitated vessels. Over the years various groups work on mixing in those stirred and agitated vessels using both new experimental and computational methods, like for example Barrue, who focuses on particle trajectories in stirred vessels [9] and also studies mixing in the turbulent regime [10]. Important handbooks and textbooks that discuss fluid mixing and applications in process technology from a much wider perspective are those of Oldshue [11], Nienow et al [12] and Kresta [13].…”

Results are generally according to expectations: open mixers are most energy efficient, giving the lowest pressure drop, but this goes at the cost of length, while the most compact mixers require large pressure gradients to drive the flow. In compactness, the new series SMX(n), like the SMX(n = 3) (3, 5, 9) design, outperform all other devices with at least a factor 2. An interesting result is that in terms of energy efficiency the simple SMX (1, 1, 4, Â = 135 • ) outperforms the Kenics RL 180• , which was the standard in low pressure drop mixing, and gives results identical to the optimized Kenics RL 140• . This makes the versatile "X"-designs, based on crossing bars, superior in all respects.
